FAUCET on cocu;4

To all whom it 'may concern:

Be it known that I, J oHN DAVIS, citizen of the United States, residing at Vashington, in the District of Columbia, have invented certain new and useful Improvements in Faucets or Cocks, of which the following is a specification.

My invention has relation to improvements in faucets or cocks of that class known as two way cocks, and it has-for its object to simplify andimprove the construction' of this type or character of cocks over the existing prior state ot' the art.

Vith these and other objects` in view the invention consists in the novel construction and combination of parts as will he hereinafter more in detail described, and the asserted novelty specifically claimed.

I have illustrated my invention in' the accompanying drawing, in which the ligure represents my device with the Various parts assembled therein and ready for use.

Similar letters of reference indicate cor# responding parts in the ligure.

Referring to the drawing: A designates the valve casing which is provided with the usual ports a, a leading therefrom, said ports being screw -threaded with female threads upon their inner surfaces as at b, b. The upper portion of the casing A is also screw-threaded -upon its outer surface a portion of its way with male screw-threads 63.

B designates a cap provided'with an open ing C- for a purpose which will hereinafter be explained. This cap is provided upon its inner surface with lfemale threads b4 which the corresponding male threads b3 formed upon the upper portion of the casing aforesaid engage.

D designates a Valve stem which is guided through the opening in the kcap C to the upper end of which is` secured the usual handle E. i

F designates a valve which is formed in-l tegrally with and terminates in the lower part of the stem. This Valve is provided upon its outer surface with male screwthreads f within which corresponding female threads f of the casing engage. The

i inner surface of said valve is also provided .with 'female threads f3 to engage male theads 7"? formed upon the outer surface of a nipple G having its upper end i1nperforate, and at the imperforate end of this nipple and around the periphery ofthe same are provided one or more openings g. Vlien used as faucet if desired the nipple G may be dispensed with.

lH designates a tubular section, the upper portion of which is provided with male and female screw-threads, the former upon its outer surface and the latter upon its inner, the outer threads of said section engaging female threads upon the inner and lower end of the casing, and the inner threads engaging the outer and corresponding threads upon the lower and-open end of tlie nipple `which end telescopes within the upper end of the tubular sect-ion H. 'If referred the nipple Gr and the tubular section H within which it "telescopes may be formed integrally, a Valve seat g being formed at the upper end of the tubular section H upon which the lower end of the Valve is seated when closed,

and which forms an exceedingly close or eakage of water through the threaded parts when operated by the handle E to regulate the flow* or quantity of water, steam or gas through the openings in the nipple G. When steam is used suitable packing may be employed."

My device when suitably connected. with the water supply pipes of a house or other structures? to which it is adapted the advantages thereof will be readily seen ov,
